    • A system, method and an apparatus for terahertz (THz) imaging based on compressed sensing using a unified sensing mask are provided herein. The system may include a THz radiation transmitter, a window, a unified mask, a THz radiation focusing lens, a THz radiation detector and a processor to generate an image using compressed sensing. The unified mask includes a series of individual masks for filtering radiation directed at the individual masks. Each of the individual masks defines a binary two-dimensional matrix of cells that are either a radiation blocking cell or a radiation passing cell. The unified mask has a first length in a first direction. The window has a terahertz radiation blocking border that defines a terahertz radiation passing opening. The opening has a second length aligned in the first direction and the second length is less than the first length so that the unified mask is movable relative to the window to a plurality of different positions and the opening operates to select one of the individual masks at each of the positions.
    • 本文提供了一种基于使用统一感测掩模的压缩感测的太赫兹(THz)成像的系统,方法和装置。 该系统可以包括THz辐射发射器,窗口,统一掩模,THz辐射聚焦透镜,THz辐射检测器和使用压缩感测产生图像的处理器。 统一的掩模包括一系列单独的掩模,用于过滤针对各个掩模的辐射。 每个单独的掩模定义了作为辐射阻挡单元或辐射通过单元的单元的二进制二维矩阵。 统一掩模在第一方向上具有第一长度。 该窗口具有限定太赫兹辐射通过开口的太赫兹辐射阻挡边界。 所述开口具有在所述第一方向上对准的第二长度,并且所述第二长度小于所述第一长度,使得所述统一掩模可相对于所述窗口移动到多个不同位置,并且所述开口操作以选择所述各个掩模中的一个 每个职位。

    • System and method for blind echo cancellation in a received terahertz signal in a pulsed terahertz system for imaging or spectroscopy. Blind signal processing methods estimate the impulse response of the reflection mechanism and do not require a reference measurement to be taken. The reference signal may be recovered using a successive approach wherein the reference is first estimated using cross-correlation with the received signal and the received signal is represented as a function of the reference signal. For each successive echo, the calculated echo may be subtracted from the received signal and then the estimate of the reference signal is refined. Using an analytical approach, the parameters of a transfer function modeling the reflection mechanism may be estimated by optimizing a cost function.
    • 用于成像或光谱学的脉冲太赫兹系统中接收的太赫兹信号中盲目回波消除的系统和方法。 盲信号处理方法估计反射机制的脉冲响应,不需要进行参考测量。 可以使用连续方法来恢复参考信号,其中首先使用与接收信号的互相关来估计参考,并且接收的信号被表示为参考信号的函数。 对于每个连续回波,可以从接收到的信号中减去计算出的回波,然后对参考信号的估计进行细化。 使用分析方法,可以通过优化成本函数来估计对反射机制建模的传递函数的参数。
